Abstract: The present disclosure provides a method for supporting UE access control. A base station is informed by a ProSe Function via a MME or informed by the MME of information indicating whether a UE is authorized for a D2D service. The base station performs an access control to the UE according to the information indicating whether the UE is authorized for the D2D service. The present disclosure further provides a method in which a source base station informs a target base station of the information indicating whether the UE is authorized for a D2D service. The target base station performs an access control according to the information.

Abstract: The present invention provides a method for obtaining a UE counting result. The method includes: if a UE receives a UE counting message and a service corresponding to a service identifier comprised in the UE counting message is a GCSE service transmitted via a MBMS carrier, establishing, by the UE, a RRC connection; sending a UE counting response via the RRC connection; or, sending, by the UE, a RRC establishing message, and configuring a reason of establishing the RRC as MBMS UE counting. The present invention also provides a method for obtaining a UE counting result, a method and apparatus for suspending data transmission. By using the present invention, when the UE needs to receive the GCSE service, the MCE may obtain a correct counting result and not make wrong decision no matter whether the UE is in the RRC connected mode or in the idle mode. Therefore, the UE does not need to establish the point-to-point channel, and interruption of the data transmission and unnecessary power consumption are avoided.

Abstract: The present invention discloses a method for supporting ProSe configuration for a UE. In the method, a radio network node receives a ProSe configuration requirement transmitted from a UE, a ProSe function (ProSe Function), a source radio network node of the UE or a core network node to request ProSe configuration for the UE. The radio network node performs the ProSe configuration for the UE according to the ProSe configuration requirement.

Abstract: The present invention provides a method of anonymously reporting minimization of drive test (MDT) measurements. According to the method, a mobility management entity (MME) obtains MDT data anonymity configuration which indicates whether MDT measurements are to be reported anonymously at a type allocation code (TAC) level; sends a TAC of a UE to a trace collection entity (TCE) if the MDT data anonymity configuration indicates MDT measurements are to be reported anonymously at the TAC level; sends an international mobile subscriber identification (IMSI) or an international mobile equipment identity and software version (IMEISV) of the UE to the TCE if the MDT data anonymity configuration indicates other information, e.g. Trace, is adopted for anonymously reporting MDT measurements. The present invention enables an MME to send different identities of a UE to the TCE according to different requirements for anonymity to implement anonymous reporting of MDT measurements.

Abstract: This application discloses a method of using NH and NCC pairs to resolve security issues. It includes: an MME sends a sequence including multiple NH and NCC pairs to S1GW that is calculated to correspond to a UE. After the S1GW receives a UE handover message or a UE bearer switch message from a base station, the S1GW may choose a next unused NH and NCC pair from the sequence sent by the MME and send it to a target base station. In using this application, part of the bearer switch of the UE or the switch of the UE can be terminated at the S1GW or HeNB GW, which reduces impact on the bearer switch or UE handover from a base station and core network and cuts down on the use of system resources.

Abstract: Various examples provide a method for radio resources management. An MCE or a GCSE AS or a UE receives usage information of eMBMS radio resources, and adjusts radio resources in response to a determination that there is an overload state. The MCE may re-configure the eMBMS radio resources. Alternatively, the UE or the GCSE AS may establish a unicast channel for transporting a GCSE service which was transmitted on an overloaded eMBMS bearer, and release the eMBMS bearer. The technical mechanism can make effective use of radio interface resources and reduce data loss.
